Comment 1 Paul Nasrat 2004-11-12 18:09:00 UTC 
Does kudzu -p -b ddc run as root also seem slow?  It could be we're
waiting for the probe data.
Comment 2 Steven Van Impe 2004-11-12 18:45:53 UTC 
Right now both of them (kudzu and display config) take about 5
seconds, is this considered slow or normal ?

The output from kudzu seems correct expect for this:
mem: 16384
Does this mean kudzu thinks my graphics card only has 16MiB of RAM (it
has 128) ?
Comment 3 Paul Nasrat 2004-11-15 14:29:59 UTC 
OK looks as if ddc probing is slow on your h/w.  Can you paste the
output of the kudzu probe into the report.

Comment 5 Bill Nottingham 2004-11-15 18:49:57 UTC 
Can you attach the output of 'strace -tt /usr/sbin/kudzu -p -b ddc'?
Comment 6 Steven Van Impe 2004-11-15 21:00:42 UTC 
That file is 33MBs big, are you sure you want me to upload it ?
For now, I'll upload a short version of it, since the majority of the
original file contains the same message over and over again.

What does 'cat <whatever> | grep vm86 | wc -l' say?
Comment 9 Steven Van Impe 2004-11-16 18:50:58 UTC 
[steven@max ~]$ cat strace.txt | grep vm86 | wc -l

Comment 10 Bill Nottingham 2005-09-28 21:10:50 UTC 
Realistically, this code is not going to change appreciably in the near future
in a way that would speed this up. Hence, closing this report.
